Expression of , , and genes in aortic dissection.

Thoracic aortic dissection (TAD) is a highly lethal disease occurring inside the aortic wall and is characterized by matrix degradation. Matrix metalloproteinases (MMPs) are members of a large endopeptidase family that function in the degradation of the extracellular matrix (ECM) proteins, the maintenance of the ECM, and the regulation of signaling in the aorta. MMPs are found in tissue with their natural inhibitors.

Epigenetic and Genomic Hallmarks of PARP-Inhibitor Resistance in Ovarian Cancer Patients.

Background: Patients with advanced-stage epithelial ovarian cancer (EOC) receive treatment with a poly-ADP ribose-polymerase (PARP) inhibitor (PARPi) as maintenance therapy after surgery and chemotherapy. Unfortunately, many patients experience disease progression because of acquired therapy resistance. This study aims to characterize epigenetic and genomic changes in cell-free DNA (cfDNA) associated with PARPi resistance.

V617F Mutation in Endothelial Cells of Patients with Atherosclerotic Carotid Disease.

Objective: It has been shown that clonal mutations occur in hematopoietic stem cells with advancing age and increase the risk of death due to atherosclerotic vascular diseases, similarly to myeloproliferative neoplasms. Endothelial cells (ECs) and hematopoietic stem cells develop from common stem cells called hemangioblasts in the early embryonic period. However, the presence of hemangioblasts in the postnatal period is controversial.

Metabolic pathways of potential miRNA biomarkers derived from liquid biopsy in epithelial ovarian cancer.

Epithelial ovarian cancer (EOC) is the type of OC with the highest mortality rate. Due to the asymptomatic nature of the disease and few available diagnostic tests, it is mostly diagnosed at the advanced stage. Therefore, the present study aimed to discover predictive and/or early diagnostic novel circulating microRNAs (miRNAs or miRs) for EOC.

Different perspectives on translational genomics in personalized medicine.

Personalized medicine is a relatively new and interesting concept in the medical and healthcare industries. New approaches in current research have supported the search for biomarkers, based on the genomic, epigenomic and proteomic profile of individuals, using new technological tools. This perspective involves the potential to determine optimal medical interventions and provide the optimal benefit-risk balance for treatment, whilst it also takes a patient's personal situation into consideration.

Integrated bioinformatics analysis of validated and circulating miRNAs in ovarian cancer.

Recent studies have focused on the early detection of ovarian cancer (OC) using tumor materials by liquid biopsy.

This study aims to reliably perform functional analysis of previously validated circulating miRNAs' target genes by using pathfindR.

Assessment of the Role of Nuclear ENDOG Gene and mtDNA Variations on Paternal Mitochondrial Elimination (PME) in Infertile Men: An Experimental Study.

In humans and most animals, maternal inheritance of mitochondria and mitochondrial DNA (mtDNA) is considered as an universal assumption. Recently, several lines of evidence suggest that different species seem to employ distinct mechanisms to prevent the inheritance of paternal mtDNA. There are few studies in the literature on the molecular basis of sperm mtDNA elimination in mammals and paternal mtDNA transmission in humans.

Microrna analysis of human decidua mesenchymal stromal cells from preeclampsia patients.

Introduction: In preeclampsia (PE), human decidua mesenchymal stromal cells (hDMSCs) are exposed to abnormally high levels of oxidative stress and inflammatory factors circulating in the maternal blood. MicroRNAs (miRNAs) have been shown to have a significant impact on the differentiation, maturation and function of mesenchymal stromal cells (MSCs). Our aim in the present study is firstly to investigate differentially expressed miRNA levels to be used as a biomarker in the early detection of PE and secondly to investigate whether those differentially expressed miRNAs in hDMSCs have an effect on the pathogenesis of PE.

Potential function of microRNAs in thoracic aortic aneurysm and thoracic aortic dissection pathogenesis.

Thoracic aortic aneurysm (TAA) and thoracic aortic dissection (TAD) are aortic diseases known as 'silent killers'. While TAA is characterized by an enlargement of at least half of the normal aortic diameter, TAD is characterized by progressive pseudo‑lumen formation, which results in the gradual separation of the aortic wall layers. In the present study, a total of 28 serum samples from nine patients with TAA, nine patients with TAD and ten healthy individuals were studied.

Potential biomarker of circulating hsa-miR-1273g-3p level for detection of recurrent epithelial ovarian cancer.

Purpose: Ovarian cancer (OC) is first gynaecologic cancer that causes women death and epithelial ovarian cancer (EOC) is the most lethal ovarian cancer type. While treatment is commonly successful, some cases (10-20%) show resistance to chemotherapy which is followed by recurrence. MicroRNA (miRNA) based diagnosis methods are slightly important for recurrent ovarian cancer diagnosis.

Regulatory effect of miR-195 in the placental dysfunction of preeclampsia.

Preeclampsia (PE) is a pregnancy specific disease soon after 20 weeks of gestation where major symptoms are hypertension and proteinuria. The underlying pathology is believed to be abnormal placentation. Epigenetic and genetic factors have significant roles in abnormal placental development.

MicroRNA expression profiling in placenta and maternal plasma in early pregnancy loss.

Early pregnancy loss (EPL), also termed early miscarriage, is determined as the unintentional expulsion of an embryo or fetus prior to the 12th week of gestation. EPL frequency is ~15% in pregnancies. Fetal development and growth is associate with placental function and vessel development; therefore, the placental genome would represent a useful miscarriage model for (epi)genetic and genomic studies.

Expression profiling of maternal plasma and placenta microRNAs in preeclamptic pregnancies by microarray technology.

Preeclampsia (PE) is one of the leading causes of maternal and fetal morbidity and mortality, occurring usually in the second half of pregnancy and affecting approximately 5-8% of pregnancies in the world. miRNAs play critical role in the regulation of placental development processes. We aimed to determine specific novel miRNAs for early diagnosis of preeclampsia which is one of the most dangerous pregnancy diseases.
